OPERA-GLASS.

SPECIFICATION forming part of Letters Patent No. 370,975, dated October4, 1887.

Application filed December 4, 1886. Serial No. 220,681. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK SonEIDIe, of the city, county, and Stateof New York,

have invented a new and Improved Opera- Glass, of which the following isa full, clear, and exact description.

The object of my invention is to provide a new and improved operaglass,which can be held Very conveniently to the eyes, can be focused easily,is ornamental in appearance, and very handy to carry.

The invention consists of an opera-glass pivoted in a casing having ahandle, of means for moving the opera-glass into a position at rightangles with the casing, and of means for adjusting the focus of theopera-glass while in the latter position.

The invention also consists of various parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings,'forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the iigures.

Figure lis a front elevation of mymprovement in a closed position. Fig.2 is a side elevation of the same. Fig. 3 is a sectional front elevationon the line x x of Fig. 4, showing theimprovement in an open position.Fig. 4 is a sectional plan view of the same on the line yy of Fig. 3,and Fig. 5 is a sectional front elevation of part ofmy improvement onthe line .e .e of Fig. 4.

The opera glass A is provided with the frame B, pivoted on the sleeve C,held on the bolt D, secured in the upper part of the casing E, which isopen on one side -and is provided on its lower end with a handle, F, ofany suitable form and shape. The opera-glass A is provided with theusual objectives, each held in casings G, secured yrigidly to the frameB. In each casing G telescopes the extensiontube G', secured by itsouter end on the cross piece or plate H, and in each tube G' teles-"copes the extension-tube G2, carrying the eyepieces and secured to thecross piece or plate I.

A spiral spring, J, is secured by one end to the frame B and by itsother end to the said sleeve C, and has the tendency to throw the frameB into its outer position. (Shown in Figs. 3 and 4.) The sleeve C isprovided with teeth O', which engage a spring-catch, C2, secured to theframe B and serving to hold the sleeve C in any desired position, thuspermitting of regulating the tension of the spring J' by disengagiug thespring-catch Cl from the teeth C' and then turning the sleeve C untilthe desired tension of the spring J, held on the said sleeve, isattained. Ihe catch C2 is then again engaged with the teeth C', and thesleeve is thus held in place.

On the bolt D is mounted, to revolve,a sprocket-wh eel, K, overwhichpasses asproeketchain, K', also passing over a sprocket-wheel, K2,secured to the sleeve K3, adapted to rotate in suitable bearings ou theframe B, and also turning on the collar or sleeve L, secured in themiddle of the cross-piece H, and telescoping in the said sleeve K3. Inthe sleeve K3 is held a flanged nut, N, screwing on the double nut O,having the annular flange O', which, with the iiange of the nut N,incloses the inwardly-extending flange L of the sleeve L, so that thelatter moves laterally with the double uut O. The latter is providedwith an interior screw-thread, on which screws the screwbolt P, securedto the frame B, and is also pro vided with an exterior screw-thread, onwhich screws the nut Q, adapted to telescope iu the sleeve L, andsecuredby its outer end to the cross-plate I.

The sprocket-wheel K is secured to a second sprocket-wheel, R, overwhich passes an endless sprocketchain, R', extending downward andpassing over the sprocket-wheel R2, turning on the bolt D', secured inthe lower part of the casing E. The sprocket-wheel R2 is attached to awheel, S, turning on the same bolt D', and provided with a milledperiphery. The wheel S extends on each side of the casing E, as shown inFigs. l and 3.

The pivoted end of the frame B is provided lwith a shoulder, T, (seeFigs. Band 5,) which engages, when the frame is in the outerposition,with the springcatch T', pivoted on the casing E and projectingslightly with its outer end on one side of the said casing, as shown inFigs. l and 5. A similar shoulder, U, is formed on the outer end orlower part of the frame Band engages with a similar springcatch,U',pivoted on the lower part of the cas- IOO ing E, and also extending withone end from the open side of the casing E, as shown in Figs. l and 3.The catches T and U are preferably spring-catches-that is,a catchwhichis always held in a normal position by a spring, so as to engagethe corresponding shoulder,T or U, firmly and securely. i

The operation is as follows: The opera-glass A is held inaclosedposition, asshownin Figs. l and 2, by the spring-catch U engagingthe shoulder U on the frame B of the glass. In this position theopera-glass is fully protected from dust, Sie., and is very handy tocarry. When it is desired to use the glass, the operatorpresses ontheprojecting end of thespringcatch U and disengages the shoulder U, so

that the glass now swings into a position at right angles to the casingE, as shown in Figs. 3 and 4., by the action of the spring J. The glassis held locked in this position by the shoulder T of the frame Bengaging the springcatch T. The opera-glass can now be held to the eyesand focused by turning the milled wheel S, so that the sprocket-chain Rand the sprocket-wheels R and K are set in motion,

Yand the latter imparts its motion by the sprocket-chain K to thesprocketwheel K2. The rotation of the latter turns the double nut O,which screws outward on the screw-bolt P and carries the sleeve L andits cross-plate H with it, and thev latter draws the tubes G outward. Atthe same time the rotation of the double nut O causes an outwardmovement of the nut Q and its cross-plate I, thus drawing the tubes G2,carrying the eyepieces, out-ward. It will be seen that the operator canthus focus the operaglass A from the lower part lof the casing E. Thetubes G and Gr2 of the opera-glass A are teleseoped inward by turningthe wheel S in an opposite direction, and the opera-glass A, after beingclosed, can be brought back to its casing E by disengaging thespring-catch T from the shoulder T and then pressing the glass A, whichswings on the bolt D, downward until the shoulder U of the frame Bengages the spring catch U, thus locking the glassAinthecasingE.Thisdownwardswinging motion of the glass A winds up the spring J, whichis ready to move the glass upward again as soon as the spring-catch U isreleased from the shoulder U, as before described.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent'- l. The combination, with an opera-glass, of acasing in which the said glass is pivoted, substantially as shown anddescribed.
